VT machining offers CNC Plasma Cutting for 1020 Steel (UNS G10200 / C22 / S20C), typically supplied hot-rolled or cold-drawn. Close to 1018 with slightly lower Mn; general machined parts.
CNC Plasma Cutting Notes for 1020 Steel
Plasma is a fast, economical option for thicker 1020 Steel plate where edge finish is less critical.
For estimating, a 100 × 100 × 10 mm block of 1020 Steel weighs about 0.79 kg.

Request a QuoteFrequently Asked Questions
What tolerances can you hold for CNC Plasma Cutting 1020 Steel?
Achievable tolerances for 1020 Steel cutting depend on the alloy, geometry and feature size. Laser cutting holds contour tolerances to around ±0.05 mm depending on thickness. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom 1020 Steel parts to my drawing?
Yes. 1020 Steel cutting is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What surface finish is achievable on 1020 Steel with CNC Plasma Cutting?
Laser cutting leaves a clean cut face on 1020 Steel with a small heat-affected zone; most parts need little secondary finishing.
How clean are the edges produced by CNC Plasma Cutting on 1020 Steel?
Laser cutting leaves 1020 Steel with a narrow kerf and a clean, near burr-free edge and only a small heat-affected zone.
